"Radiation uses and ubiquitousness: The good, bad, and limits" an earlier review was published before launch of 5th Generation (5G) mobile networks technology. Now with 5G technology's upcoming use, its advantages need to be used for advancing healthcare. All this for best applications possible and as safely as possible. The review update aims at reviewing the 5G technology benefits, risks, and its reduction. All this is important for rationale use. We searched the MedLine database and relevant statutory government recommendations. Results are discussed and put in proper perspective. Advantages are higher data transmission rates, lower latency and better quality of service. 5G technology will be beneficial for health services with shortened time and space. It will aid overcoming some of the current challenges to healthcare. The advantageous applications are elaborated for (1) proper assessment, (2) pertinent treatment, (3) progress monitoring, (4) prevention applications, and (5) professional standards. The concerns about possible adverse effects to human health needs to be addressed. The health effects of frequencies in the range 450 to 6,000 MHz are cautioned. There is a need of studies on nonthermal effects of the higher frequencies. In our present state of understanding and evidence, the useful strategies suggested are the "3Rs": (1) risk-reducing devices, (2) risk-reduction necessarily, and (3) risk-reduction engineering and environment. Balancing risks and rewards are the best strategy forward. Robust communication will make excellent healthcare reach all, always and especially in times of need.
